If a shareholder fails to comply with the provisions of Article 28a of Codified Law 2190/1920, said shareholder may participate at the General Meeting only upon receiving its permission to do so.

Eligible shareholders may participate at the General Meeting either in person or through their lawfully authorized proxies. Each shareholder may appoint up to three (3) proxies.
